CUFF BUTTON.

To all whom z'-fma/ concern.'

Be it known that I, MAX C. MILLER, a citizen of Germany, and resident ofthe town of Cumberland Hill, in the county of Providence and State ofRhode Island, have invented certain new and useful Improvements in CuifButtons, of which the following is a specification.

rhis invention relates to cuff buttons of the class constructed of twomembers detachably connected together; and the object of this inventionis to provide such a cuii:1 button having means for positively ylockingthe two members of the button together when the stud-portion of onemember is inserted into the socket portion of the other member androtated a portion of a revolution by which construction the parts may bereadily connected and cannot be accidentally separated as is the casewith some constructions of separable buttons.

Vith these and other objects in view, the invention consists of certainnovel features of construction, as will be more fully described, andparticularly pointed out in the appended claims.

In the accompanying drawings:

Figure 1 is a side elevation of my improved button, showing the twoparts as connected together.

Figure 2 is a side elevation of the button, taken at a rightk angle tothe position illustrated in Figure 1.

Figure 3 is a plan view sectioned on line of Fgure 1, showing thecross-bar of the stud-member as engaging the slanting side walls of thespring to depress the same sufficiently to pass over the top of thespring into the retaining medial transverse depressions in the springarms. n

Figure 4 is a perspective view of one form of cross bar retainingspring.

Figure 5 is a face view of the base-plate of the socket portion.

Figure 6 is a top view of the socket cap,

showing the slot therein.

Figure 7 is a perspective view showing the cross bar on the end of thestud member.

Figure 8 is a modified form of flat spring for retaining' the lock-barin connected position.

With reference to the drawings, the stud member of my improved buttoncomprises a shank 10 having a head 11 at one end and a cross bar 12 atits opposite end and they wall is slotted as at 24C to permit the'passage of the cross bar 12 and the body of this cap is preferablyprovided with an inwardlyextending, annular rib 19 engaging the upperface of the plate 15 and the lower edge 20 of this cap is rolled overthe edge of the plate 15, said roll being of sufficient depth to coverthe cut-out or notched portions 16 of this plate.

Within this cap .I mount a compression spring which may be constructedin frame form, the side walls 21 of which are spaced apart and set on anangle, the base-portion 22 being turned outwardly to rest upon and slideon the plate 15 while the ends of this frame are turned downwardly as at23 to extend into the slots 16 in this plate to hold this spring againstlateral displacement when the cross bar engages the same with itsnecessary rotating action.

The middle portions of the spring arms are vbent or depressed as at 25forming a transverse socket groove into which the cross bar is adaptedto snap and t t0 retain it in locked position when rotated one-quartervturn after having passed through the receiving slot in the cap. 4

I do not wish to be restricted to this particular form of spring as insome cases instead of forming the spring of wire having spaced apartside arms, I may form the same of a flat strip of resilient metal asvillustrated in Figure 8, which is adapted to perform all of thefunctions of a spring made of wire.

I claim:

1. A separable cuff button comprising a stud member, a socket member,and a-sprin'g held against relative rotation in said socket member andprovided with a recess for receiving and releasably engaging the studend of the opposite member when said stud is passed into the socket androtated a portion of a revolution. l

2. A separable cuff button comprising a stud-member having a head at oneend and a cross bar at the opposite end, a socket member having a headat one end, and a notched plate at its opposite end, a Slotted cap onsaid plate to receive Said Cross bar and a spring in said socket havingits ends turned flown into said notehee in said plate and arranged toact :upon and releasahly retain Said @rost oarin said socket when forcedtherein against its pressure and rorated a portion of a revolution.

3. A. parahle cuff button comprising a stud-member having a head at oneend and a cross bar at its opposite end, a Socket meinher having' a postwith a head at one end retained Within said cap arranged .to aet uponand ieleasably retain the cross bar of Said opposite member Within saidcap when .passed through said slot and rotated a portion of a revolutionWithin said Cap.

In vtestimony whereof I aiX my signature.

MAX C. MILLER.
